I am guessing that most folk who have set out into the wide blue yonder (WBY) do a fair bit of research, ask lots of questions and then carefully consider their options / make their plans.

I guess we have all heard stories about folk who stocked up on 2 years of toilet rolls, baked beans or whatever before setting off into the YBW........cos' abroad might not have any

But I am just curious about what folk carefully planned for / bought in bulk / worried about / modifications you made to the boat / equipment you bought.........and with hindsight and experiance realise that you didn't actually need to do at all / need to do quite so thoroughly / didn't need to worry about so much before departing into the YBW - either because from their just having been no need or you have found that "abroad" do actually sell toilet rolls (etc!)
